Our Compress PNG tool is free and works on any web browser. Plus, all files are protected with 256 bit SSL encryption and deleted automatically after 2 hours. Your file security and privacy are guaranteed.
Our PNG compressor converts 32-bit truecolor PNGs with alpha channel to palette PNG (8-bit indexed color image). This stripping of colors by combining similar colors, while lossy, is often not noticeable to the human eye . We also strip image metadata to further reduce PNG file size. Additionally, you can also resize your PNGs to further reduce their file size .
